What about safety is fair? Tesla should have to provide evidence that it's as safe as what it's replacing.

For comparison, 3 minutes on google turned up a thesis by Chris Post at MIT comparing alternative steering interfaces for "next generation" electric vehicles, including yokes. Apparently they were more difficult to use and had worse performance across almost all metrics, especially braking time. Maybe Tesla's implementation resolves these issues, but they should demonstrate that.

I'm surprised gdb wouldn't automatically consult /proc/PID/exe to read symbols. It seems more reliable than checking argv[0] and then reading the file at that path.
It does address the problem. However, it also scares away users and fractures the market.
The issue isn't when you have form and function. The issue is when you have form over function.
AOC is such a firebrand. I love it. Not a lot of politicians who give me the sense that they're actually fighting for me.
There is no the answer, but we sure might get an answer.
>So now Tesla is said to be innovating when they adopt old technology invented by others?

You mean like ... an electric car?

Listen to yourself: "Tesla is the Apple of cars" They took something that already existed (electric cars), re-engineered it and created something truly innovative.

I believe there will be a big journalist investigation about how some pretty influential investors made Robinhood management do what they did.

You're right, they don't care about you talking securely to your bank or any other company that they can trust to keep logs of the plaintext.

It might be less disingenuous for governments to say that they are actually against Citizen-to-Citizen encryption.
variable rate steering racks absolutely exist - early 2000s BMW 5 series and honda S2000 are the ones off the top of my head.

They are not common. Mostly nowadays a similar effect is created via variable assist. Human interface-wise, nonlinear controls are REALLY not a great idea without specific training.

If you look at airplanes, where pilots are type rated, you have a lot more controls mixing with electronic flight controls and various regimes. The yoke/stick might control pitch at one point, angle of attack at another, altitude in another, and control surface deflection in another...or more realistically a mix of all of the above. Multiply by 6 dimensions of control.

I think about my mother. Recently we rented a Subaru Outback. I was comfortable with the minor force/lane centering control actions it took while on cruise control. She on the other hand couldn't handle it - it became a negative feedback loop. It woudl correct her into the cetner of the lane, and she responded to it as 'the car pulling' and would over react and put us in the next lane. The car correcting itself was disconcerting and provoked a corresponding reaction that was programmed in her brain as 'correct' because the heuristic was 'force through the wheel = something wrong'.

The issue here isn't whether the car does something good or bad, it is whether it does something that the average driver reacts to in a safe an appropriate way. That comes from meeting their preconceptions as to how steering behaves, unless Tesla wants to argue for type-certing their owners.
From looking at various HN comments working from home is appealing due to only one factor: personality. It appears economics, commute, child care issues, martial status, and other personal indicators are largely irrelevant. People that can handle being away from social interactions appear to love working from home while people who need social interaction do not regardless of whether all other personal indicators are stressors.
Exactly this. They know there will be lawsuits and they know there might be SEC fines, but they are betting that those two will total up to be less than the billions it would cost them to cover a short position at $500-$600 per share.

The question I have is, can this be prosecuted criminally and can those in charge be threatened with actual jail time from this?
Fix: fines should be 2x more than just taking the loss on the chin.
I'll simply ask gdb to dump its memory, then I extract my command from its coredump. For example,

$ bash
$ echo $$

$ while true ; do echo 1 ; echo 2>/dev/null ; sleep 30 ; done

# From now on, this command cannot be stopped, and by now
# the text has been overwritten by new output...

Open a root shell, install gdb.

Studying the source code and calling C functions in a debugger, like the author did here, is a clever and accurate way to solve this problem and deserves its pages in sysadmin folklore, but I think my brute-force approach, although boring, is equally acceptable. It's also safer, a wrong function call won't crash the program. If I can not find what I need immediately, analyzing the coredump safely in a debugger (perhaps on my own machine with more devtools installed, with a cup of tea) is also an option for me.
Citadel Securities is a market maker. Do you have any evidence that Citadel has un-hedged "massive short positions on GME"?

I find it nuts how this has transformed into a populist thing.
Nice work! Can I add your site to https://weirdweb.netlify.app
I would think almost the opposite. The prices are high where there are high incomes--California, NY, Boston, Washington...

If you don't need to chase a high income, you can move where there's cheaper rent and try to innovate there. Assuming that you don't need any of the spatial resources of the expensive areas. (A big if... but perhaps you can grow your idea then move to the areas with lots of capital.)
ON the contrary, I think HN is a good example of the open web, a protocol based around pages hosted in all manner of places and links between them. HN is one of many places you could go to find recommendations for content hosted elsewhere.

Hosting comments is platformy, but other than that HN doesn't try to get people to host content on HN, and while dang can decide that HN won't recommend a particular piece of content, he cannot remove that content from wherever it's hosted (except by recommending it too much and hugging the server to death).

This seems to be interpreted as a meritocracy vs. oligarchy sort of thing. I agree with the basic takeaways there (about opportunity, resources, discrimination, network effects, etc.), but even if we had a meritocracy, I'm not sure this would be an unexpected outcome.

Since when did anyone think the smartest people, those with the best booklearnin learning acquisition, would be the best entrepreneurs? I don't know that the biggest Ayn Rand cultist would have that expectation. It's equally plausible that the traits that lead to entrepreneurship are heritable but not learning-related.

With your money. Most people are trading on margin, because they're gambling addicts.

EDIT: I'm not sure if it's most that are trading on margin. Certainly it's everyone I've seen, but people who share their trades publicly are probably not representative.
The tooling is solid, the lsp server provides auto completions and edit by edit syntax checking in major editors like vim, Emacs and vscode, there is a good formatting tool in elm-format, a built in repl which is basic but works fast. A test runner is also there, with support for fuzzing. Not to mention a time travel debugger which is a highlight.
Things that are missing or not good are proper logging, step by step line debugger, profiling and performance tracking.

This is an interesting point. But being banned from a small forum feels like disassociation. Being banned from a huge central platform—the de facto public square—feels a lot less like free speech.

Maybe a better way of thinking about this is that “free speech” on the Internet is about decentralization of small communities even if many of those communities themselves skew authoritarian? If you are banned from a small private gathering, everyone’s practical speech rights remain in-tact. You aren’t banned from the larger system.

Before a couple years ago (when elastic started digging deeper into the paid addon realm), I don't think they could've forked and been able to keep enough compatibility / community around their fork to make it as useful and compatible with everything Elasticsearch did.

But today, I think they have a 50/50 shot of the Amazon-forked ES version becoming the de-facto standard, and Elastic's fading into obscurity.
That is not what that tweet is saying. She is saying that particular pattern, sales allowed but purchases are restricted, is especially deserving of an investigation.

This article misinterpreted the survey. 91% of people don't want to work from home, 91% want it as an option, and that's only people who are currently working from home who used to not.

57% seems more accurate: "But once the crisis is over, most (57%) of those who were working before the outbreak and who intend to stay part of the workforce say they want to be able to continue working from home."

Airbus moved away from yolks on their planes as part of a move towards greater automation, with great success. Same arguments were made there BTW.

The market for utilitarian design is high. Tesla's for example have some of the LOWEST injury rates per mile driven. The whole package (which is how this all should be judged) is safer than many cars driving on the roads today.

A design that for example allows someone to drive faster than 10MPH (which clearly reduces safety) should be condemned?

I condemn this type of absolutely ridiculous over the top language use and this ridiculous absolutism.
There is a fantastic quote in the comments:

Yes, I was deeply into the McDougall Program, even went to the week long training. I lost a bunch of weight on it. Then it seems that my body adapted and without changing the ingredients, my appetite returned, and so did the weight.

Something similar happened to me with a low carb paleo diet years later. I've had to become more extreme to succeed. But I think that's because of the damage I've done to my own metabolism with a fork and spoon, and isn't true for most people.

Most people, I think, would benefit greatly from changing to a complex carb diet from a Standard American Diet.
That is exactly what is happening right now.

After Melvin Capital loses billions with their naked shorts, Citadel and other hedge funds short selling take over to pulls the strings from underneath some trading apps, including Robinhood.

Will be interesting to see where this lawsuit will go, since it looks like a clear coordinated manipulation of heavily shorted stocks and blocking everyone else from buying them.

The correlation is that both installation steps are happening in the same assembly line, in the same conditions, by the same workers/robots. Panel installation is a solved problem. Brake installation is a solved problem. Electronics installation is a solved problem.

Except one of those solved problems very clearly isn't "solved." This is something that stops assembly lines in other manufacturers. That it doesn't with Tesla signals that other assembly-line-stopping issues may also be ignored.

What I think we need is Interoperability, not just protocols. What I understand by interoperability is what a mature (spoken) language provides. Although its body of words remains pretty much fixed, it offers a wide range of expression. I think that what we need is a language of the internet to achieve this type of interoperability. So, in a way, a language can be seen as a communication protocol and, with such a language, two systems can talk and discover and consume each other's services. This language shouldn't change too much, but it should be complex enough, to start with, in order to allow a high degree of expression and, ultimately, interoperability.

There’s a huge glut of therapists, they just only want to have clients who pay out of pocket because then they offload the work of any insurance reimbursement, paperwork or other overhead to the client. She also suggested therapists want good filters to avoid difficult clients, like low-income clients that have a hard time paying and have more difficult social or behavioral issues.

Scraping data from r/WallStreetBets for Numerai Signals
no the pump and dump part means that WSB arguably exists as a kind of ion cannon like Anon used to be, where if you can convince a sizable number of community members to commit to a proposed course of action, you can create a reflexive effect that you can harness to your advantage. creating a stock price event, on purpose, using a community like WSB, and profiting, by exiting the trade is a "pump" and "dump."

it is ancillary that a short squeeze might be an attendant and inciting event. you could do this with any stock as long as the supply is limited compared to the demand created by the manipulation of trader sentiment. the short squeeze just amplifies the effect
